PREFACE. 


THE  first  edition  of  this  book  was  prepared  for  the  press  during  the  evenings  and  Satur- 
days of  tne  month  of  January,  1879.  The  hope  that  an  abler  hand  would  undertake  the 
task  deferred  the  beginning,  and  the  needs  of  a  class  of  over  five  hundred  pupils  hastened 
the  completion  of  a  work  that  would  have  been  more  slowly  elaborated  had  the  reputa- 
tion of  the  author  been  the  only  consideration.  The  errors  incident  to  such  rapid  work 
were  as  far  as  possible  corrected  the  following  year,  in  a  second  edition,  which  was  pre- 
faced as  follows: 

m 

"I  have  endeavored  to  prepare  an  inexpensive  manual  which  will  enable  beginners  in 
botany  to  determine  the  names  of  all  plants  with  conspicuous  flowers  that  may  be  found 
growing  wild  in  the  Central  Valley  of  California  from  Visalia  to  Marysville,  and  through 
the  Coast  Ranges  from  Monterey  to  Ukiah.  Over  six  hundred  species  of  plants  are 
characterized  by  descriptions  condensed,  for  the  most  part,  from  Vol.  I  of  the  'California 
Botany, 'and  Sereno  Watson's  'Revision  of  the  North  American  Liliaccoe.'  Valuable 
material  has  also  been  obtained  from  a  'Revision  of  the  Eriogonese,'  by  Torrey  £  Gray, 
Gray's  'Synoptical  Flora  of  North  America,'  and  'Gray's  Manual  of  Botany.' 

"Plants  belonging  to  the  Parsnip,  Aster,  Willow,  Oak,  and  Pine  Families,  are  not  de- 
scribed, being  mostly  too  difficult  for  beginners,  or  of  little  interest  to  them.  The  Intro- 
ductory Lessons  are  designed  to  show  the  learner  how  to  study  the  growth  of  plants,  as 
well  as  to  give  such  knowledge  of  their  structure  as  will  enable  him  to  understand  the 
descriptions  in  the  Flora.  The  'Glossary  of  Generic  and  Speciiiu  Names '  will  enable  the 
student  to  make  appropriate  common  names  for  most  plants. 

"To  the  authors  whose  works  have  furnished  the  materials  for  this  book  is  due  the 
credit  for  whatever  of  excellence  it  may  possess;  to  the  compiler,  who  may,  in  a  few 
cases,  have  misrepresented  these  authors,  attaches  the  blame  for  most  of  its  defects. 

"I  am  indebted  .for  suggestions  and  criticisms  to  Prof.  E.  W.Hilgard,  Dr.  C.  L.  Ander- 
son, Prof.  W.  H.  Brewer  and  Dr.  Asa  Gray.  To  the  latter  I  am  especially  grateful  for 
his  kind  interest  in  my  humble  work." 

One  third  of  the  second  edition  was  new  matter,  and  only  about  half  of  the  book  in  its 
present  form  is  printed  from  the  stereotype  plates  of  the  first  edition.  The  newer  half 
of  the  work,  although  necessarily  partaking  somewhat  of  the  nature  of  patchwork,  is  as 
good  as  I  can  make  it.  My  drawings  upon  wood  have  been  faithfully  engraved,  and, 
though  claiming  no  artistic  merit,  will,  I  trust,  prove  helpful  to  the  learner.  With  few 
exceptions — always  noted  in  the  text — the  plants,  or  parts  of  plants,  are  represented  of 
the  natural  size.  Besides  the  more  obvious  improvements,  an  entirely  new  Analytical 
Key  replaces  the  old  one;  and  our  most  common  oaks  are  described.

T  PREFACE. 

Assuming  that  facts  in  natural  history  are  useless  if  merely  memorized  from  the  book, 
and  that  the  student  must  earn  his  knowledge  by  observing  and  experimenting,  it  is  ob- 
viously best  to  encourage  him  at  first  by  showing  him  how  to  try  simple  experiments 
whose  results  are  easily  interpreted.  Seeds  are  the  best  material  for  such  experiments, 
since  the  phenomena  connected  with  their  germination  are  not  only  easily  observed,  but 
deeply  interesting.  For  this  reason  what  may  seem  a  disproportionate  space  in  the  Intro- 
ductory Lessons  is  devoted  to  "The  Beginnings  of  Plant  Life."  There  are  no  lessons  of 
greater  educational  value  than  those  given  to  observing  eyes  by  the  growth  of  a  plant 
from  the  first  quickening  of  the  dry  embryo  to  the  putting  forth  of  flowers  and  the  ripen- 
ing of  fruit.  A  sunny  window  in  each  school-room  should  be  devoted  to  these  beautiful 
object  lessons  of  nature.  It  must  not  be  forgotten,  however,  that  since  most  young  peo- 
ple are  eager  to  learn  the  names  of  plants  whose  flowers  they  admire,  it  is  best  to  devote 
most  of  the  spring  months  to  the  study  of  Systematic  Botany.  The  child's  "What  is 
it?"  and  the  finger  pointing  to  the  plant  in  bloom,  show  plainly  with  what  to  begin  the 
study  of  botany.  Baron  Frederick  von  Mueller  says  in  his  preface  to  an  elementary 
work  upon  the  botany  of  Victoria,  Australia:  "An  experience  of  nearly  forty  years  has 
convinced  the  author  that  the  use  of  a  grammar-like  publication  for  initiating  into  a 
study  of  plants  is  alike  wearisome  to  teacher  and  children,  and  that  as  a  rule,  subject  to 
rare  exceptions,  the  knowledge  acquired  from  the  ordinary  first  elementary  works  on 
botany  is  as  quickly  lost  as  gained.  The  only  method  of  rendering  such  studies  agreeable 
and  lastingly  fruitful  consists  in  arousing  an  interest  of  the  young  scholars  in  the  native 
plants  of  their  locality,  to  afford  them  all  possible  facilities  to  recognize  and  discriminate 
all  the  various  plants  within  reach,  to  lead  them  by  observations  thus  started  to  com- 
prehend the  limits  of  specific  forms,  of  generic  and  ordinal  groups,  and  to  conduct  them 
afterwards  to  the  more  difficult  study  of  special  anatomy  and  physiology  of  plants." 

Teachers  and  learners  arc  here  reminded  of  the  importance  of  carefully  writing  out 
the  details  of  experiments  tried,  as  well  as  descriptions  of  what  has  been  observed.  In 
the  words  of  Dr.  Asa  Gray:  "  The  naturalist  must  not  only  observe  that  he  may  describe, 
but  describe  if  he  would  observe." 

It  will  be  noticed — and  the  fact  has  formed  the  basis  of  a  criticism — that  the  descrip- 
tions of  genera  and  species  in  this  Flora  are  very  brief;  as  a  rule  only  the  contrasting 
characteristics  being  given,  since  more  is  calculated  to  confuse  rather  than  help  the  be- 
ginner. Dr.  Gray  says:  "In  floras,  as  in  more  general  works,  abridged  descriptions  or 
diagnoses  suffice — indeed,  are  preferable  in  all  cases  where  the  region  is  pretty  well 
explored,  and  where  materials  can  be  thoroughly  elaborated." 

Although  the  Flora  is  designed  especially  for  students  in  Central  California,  it  will  be 
found  only  a  little  less  useful  to  those  studying  as  far  south  as  Los  Angeles,  or  as  far 
north  as  the  Columbia.  The  Introductory  Lessons  are  suited  to  the  entire  Pacific  Coast.

STRUCTURAL    BOTANY. 


SUCTION  1.— THE  BEGINNINGS     OF   PLANT  LIFE. 

1.  If  the  first  rain  of  the  wet  season  is  followed  by  warm,  sunny- 
weather,  specks  of  green  will  soon  appear  among  the  dry  stems  of  last 
year's  weeds;  and  in  fence  corners  or  other  eddy  nooks  where  summer 
winds  have  drifted  seeds  and  covered  them  with  dust,  you  may  find  per- 
fect mats  of  baby  plants.  With  a  shovel  skim  off  a  few  square  inches  of 
this  plant-bearing  soil,  and  carefully  examine  it.  Except  a  few  green 
needles,  which  you  recognize  as  spears  of  grass,  most  of  these  little  plants 
seem  to  consist  of  white  steins,  which  split  at  the  top  into  pairs  of  green 
leaves.  Looking  sharply,  you  may  find  between  each  pair  of  leaves  a

tiny  bud;  or,  in  the  older  plants,  this  may  have  grown  other  leaves,  which 
curiously  enough  are  not  like  the  first  two.  (Figures  1  to  6).  Searching 
through  the  shovelful  of  earth  you  will  likely  find  plants  in  all  stages  of 
growth,  from  swollen  and  sprouting  seeds  to  stems,  which  are  just  push- 
ing their  bowed  leaf-heads  into  the  sunlight.  Here,  then,  is  material 
from  which  you  may  learn  how  plants  grow;  a  lesson,  remember,  which 
no  text-book  or  schoolmaster  can  teach  you.  It  will  be  easier,  however, 
since  most  of  these  early  wild  plants  come  from  very  small  seeds,  to  take 


VI  INTRODUCTORY    LESSONS. 

your  first  lessons  from  plants  which  have  larger  beginnings.    You  should 
first  study — 

2.  The  Plant  in  the  seed.     Get  many  kinds  of  large  seeds,  such  as 
peas,  beans,  squash-seeds,  buckeyes,  castor  beans,  corn,  etc.     Put  them 
in  water  that  they  may  become  soft  enough  to  be  readily  separated  into 
their  parts.     In  a  day  or  two  starchy  seeds,  such  as  peas  or  beans,  will  be 
in  good  condition. 

3.  First  take  a  bean  and  make  drawings  showing  the  outlines  as  seen 
nidewise  and  edgewise.     Any  marks  that  seem  to  be  found  on  all  beans 
must  be  put  down  in  the  drawing,  but  do  not  bother  about  the  shading. 
These  attempts  to  represent  what  you  see  will  lead  to  the  discovery  of 
certain  marks  on  the  concave  edge  of  the  bean,  the  meaning  of  which 
you  may  sometime  learn  by  studying  the  growth  of  the  seed  in  the  pod. 
After  you  have  thus  studied  the  outside  of  the  seed,  slit  it  along  the  back 
with  a  sharp  knife  and  take  out  the  kernel.     It  readily  splits  into  halves 
which  are  held  together  near  one  end  by  a  short  stem.     Upon  breaking 
them  apart  the  stem  sticks  to  one  half,  and  you  discover  growing  from  the 
inner  end  a  pair  of  tiny  embracing-leaves.     Make  another  drawing  and 
compare  it  with  Fig.   7.     Presently  it   will  be 

clear  to  you  that  this  entire  kernel  is  a  littlo 
plant.  The  plant  in  this  dry  apparently  lifeless 
first  stage  of  its  existence  is  called — 

4.  The  Embryo,  or  Gsrm.      This,  as  you  have 
seen,  is  made  up  of  the  stem,  or  Radicle ;  the 

thick  parts  called  Cotyledons,  and  the  two-leaved          7  8

embryo  of  a  peanut.  The  radicle  is  not  bent  around  against  the  cotyle- 
dons as  in  the  pea  and  bean,  and  the  plumule  shows  two  divided  leaflets. 
The  cotyledons  of  the  squash  are  thin  and  the  plumule  is  scarcely  visible. 
Lupine,  though  its  seeds  resemble  beans,  has  a  long  radicle  and  a  minute 
plumule.  The  buckeye  seems  to  have  a  long  radicle,  but  since  it  splits 
nearly  to  its  point,  where  you  will  find  a  large  plumule,  it  is  evident  that 
the  apparent  radicle  is  mostly  made  up  of  the  cotyledon  steins  (petioles).

5.  Albuminous  Seeds.  Remove  the  shell-like  coat  of  a  castor  bean, 
and  carefully  split  it  flatwise.  What  at  first  seems  to  be  a  large  plumule 
proves  to  be  free  from  the  rest  of  the  kernel,  and  with  care  you  may  be

able  to  get  it  out  whole  (Fig.  10.)  It  is  a  straight  embryo  with  beautifully 
veined,  leaf-like  cotyledons,  embedded  in  a  white,  oily  substance,  which 
makes  up  the  mass  of  the  kernel.  This  substance  is  called  Albumen,  a 
name  which  applies  to  anything  inclosed  with  the  embrj'o  by  the  seed 
coats.  Peas,  beans,  acorns,  nuts,  and  most  large  seeds  have  no  albumen. 
Carefully  cut  thin  slices  from  a  well  soaked  coffee  grain  until  its  embryo 
appears  as  represented  in  Fig.  12.  The  horny,  folded  albumen  makes 
up  most  of  the  seed.  A  similar,  but  smaller  embryo,  may  be  found  in 
the  brain-shaped,  fleshy  albumen  of  the  ivy  seed.  The  embryo  of  the 
Tree-Datura,  or  Stramonium,  is  shown  in  Fig.  11. 
It  has  slender  cotyledons,  folded  down  against  a 
thick  radicle,  the  whole  embedded  in  tough,  fleshy 
albumen.  Take  the  embryo  of  a  Morning-Glory 
seed  and  pick  the  bits  of  transparent,  jelly-like 
albumen  out  of  the  pockets  in  the  crumpled  coty- 
ledons. An  attempt  to  flatten  out  the  cotyledons 
will  probably  result  in  something  like  6,  Fig.  13, 
which  may  lead  you  to  suppose  that  the  coty- 
ledons are  separately  crumpled,  which  is  not  the 
case.  They  stick  closely  together  by  their  inner 
faces,  as  do  the  cotyledons  of  other  seeds  you  have 
examined,  and  they  are  crumpled  as  one;  but,  being 
notched  at  the  end,  they  readily  split  down  the 
center.  Buckwheat  seeds  will  give  you  some  trouble.

Indeed,  it  will 


Vlll  INTRODUCTORY    LESSONS. 

be  much  easier  to  make  out  the  exact  shapes  and  positions  of  the  em- 
bryos in  most  albuminous  seeds  after  they  have  begun  to  grow. 

Monocotyledonous  Embryos.  Corn,  wheat,  oats,  and  possibly  a 
few  other  seeds  in  your  collection,  are  different  in  plan  from  any  yet 
described.  In  corn  the  soft  portion  called  the  chit  is  the  embryo.  Wheat 
and  oats  have  smaller  but  similar  embryos.  You  cannot  easily  distin- 
guish the  parts  of  these  embryos,  but  you  can,  at  least,  determine  that 
they  have  not  two  cotyledons.  Really  they  have  one  cotyledon,  and  are 
therefore  said  to  be  Monocotyledonous.  When  you  study  the  growing 
seeds  you  will  see  how  widely  they  differ  from  seeds  which  have — 

Dicotyledonous  Embryos.  These  are  embryos,  which,  like  the  bean, 
have  two  cotyledons.  A  few  plants  belonging  to  the  Pine  Family  have 

Polycotyledonous  Embryos.  Fig.  12  shows  the  embryo  of  the 
common  Willow  or  Digger  Pine,  which  has  more  than  two  cotyledons  in 
a  whorl  at  the  top  of  the  radicle. 

The  Germination  of  Seeds.  Plant  the  remainder  of  your  seeds— 
those  of  a  kind  together — in  boxes  or  pots  of  sand,  or  any  kind  of  loose 
soil  you  can  get.  Keep  this  little  experimental  garden  in  a  warm  place, 
where  it  can  get  a  bit  of  sunshine,  and  water  it  daily.  At  intervals  of 
three  or  four  days  dig  up  one  of  each  kind  of  seed,  and,  after  careful 
examination,  make  drawings  to  illustrate  the  successive  stages  of  growth. 
It  is  of  the  greatest  importance  that  you  repeatedly  attempt  to  draw 
what  you  see;  it  is  of  the  least  importance  that  your  drawings  are  pretty. 
You  will  learn,  among  many  interesting  facts,  that  most  seeds 
are  pushed  up  to  the  surface  of  the  ground  by  the  growth  of  the  radicle. 
There  the  seed-coats  drop  off  (except  that  in  seeds  without  albumen  the 
cotyledons  are  apt  to  slip  out  of  their  coats  on  the  way  up);  the  cotyledons 
spread  apart,  become  longer  and  broader,  and  turn  green;  lastly,  the 
plumule  becomes  a  leafy  stem.  Meanwhile,  roots  grow  from  the  lower 
end  of  the  radicle.  Some  cotyledons,  like  those  of  the  pea,  do  not  ap- 
pear above  ground,  but  send  the  plumule  up.  The  seeds  of  Big-root — 
a  pest  which  grows  in  nearly  every  field — behave  in  a  remarkable  manner. 
The  nut-like  seeds  drop  from  their  prickly  pods  in  June  or  July,  and 
soon  become  covered  with  leaves.  The  rains  of  November  and  December 
cause  them  to  sprout,  as  represented  at  d.  The  mimic  radicle — really  a

tube  formed  by  the  united  petioles, 
or  sbems,  of  the  thick  cotyledons, 
and  only  tipped  by  the  radicle — 
penetrates  the  ground  to  a  depth, 
usually,  of  four  or  five  inches.  The 
plumule  meanwhile,  as  shown  in  ft 
remains  dormant  in  the  bottom  of 
the  tubular  sprout.  "When  the  pe- 
tiole growth  ceases,  the  radicle  grows 
rapidly  by  absorbing  the  nourish- 
ment stored  in  the  cotyledons,  and 
becomes  a  tuber.  Meanwhile  the 
plumule  begins  its  upward  growth, 
splitting  the  petioles  apart,  and  usu- 
ally escaping  from  between  them,  as 
shown  in  the  figure  below  c.  In  this 
wonderful  way  the  plumule  bud  is 
deeply  planted  together  with  nour- 
ishment (stored  in  the  radicle)  which, 
if  necessary,  can  be  used  to  aid  its 
first  growth.  The  reason  for  this  curious  behavior  is  obvious,  when  w> 
know  that  ground  squirrels  are  fond  of  these  seeds,  and  that  a  severa 
frost  will  kill  the  young  plant.  If  the  seeds  wait  till  warm  weather  to 
sprout,  hungry  rodents  may  find  them;  if  they  germinate  early,  and  in 
the  manner  of  other  seeds,  Jack  Frost  may  nip  them.* 

*  Dr.  Asa  Gray,  -who  first  experimented  with  these  seeds,  found  them  to  grow  as  represented  at  a,  ii 
the  figure  [reduced  one  fourth  from  Fig.  43,  Botanical  Text-book,  edition  of  1879].  Evidently  05 
account  of  some  obstruction,  probably  the  bottom  of  a  small  pot,  the  seeds  were  elevated  two  or  threa 
uiches  above  the  surface  of  the  soil  [the  dotted  line  S  represents  the  surface  of  the  ground  for  flgurea 
a,  6,  and  c].  My  experiments  with  seeds  planted  in  shallow  boxes  gave  very  different  results — shown 
at  b,  which  is  a  reduced  copy  of  Fig.  14  of  second  edition.  The  plants  came  up  about  four  inches  from 
where  the  seeds  urere  planted,  the  plumule  being  pushed  laterally  that  distance  by  the  elongation  of  tha 
cotyledon  petioles.  Such  inexplicable  behavior  stimulated  to  further  observation,  which  resulted  ia 
the  discovery  that  naturally  planted  seeds,  unhampered  by  boxes  cr  pots,  usually  grow  as  represented 
at  c  and  d.  In  one  instance  a  sprout  measured  seven  inches  Irom  the  plumule  to  the  cotyledonsl  Tht 
hairs  at  c.  probably  help  the  sprout  to  penetrate  the  soil,  by  fastening  on  to  the  surface  crust.  Curiousij 
enough,  growing  sprouts  underground  frequently  avoid  obstacles  without  touching  them.

first  the  sprouting  seeds   appear  to   be   like 
those  of  other  lupines  (see  Fig.  c),  but  when 
the  cotyledons  open,  they  are  seen  to  be  united 
by  their  broad  bases.     For  two  or  three  weeks  the 
cotyledons  enlarge;  not  only  becoming  broader,  but 
thicker;  yet  we  look  in  vain  for  a  trace  of  the  plu- 
mule.   Meanwhile  a  white  pustule  has  been  growing, 
which  finally  bursts  and  discloses  the  partly  grown 
leaves  of  the  missing  bud,  which  has  all  this  time 
been  hidden  in  the  thick  stem  below  the  cotyledons! 
Now,  the  tough  leathery  skin  of  these  cotyledons  is 
proof  against  the  nightly  frosts  that  prevail  at  this 
season  of  the  year  (December),  so  they  go  on  pre- 
paring food  from  the  air  with  which  to   feed  the 
tender  plumule,  until  it  also  is  strong  enough  to  face          c 
Jack  Frost.     If  you  carefully  examine  these  seeds  in  various 
stages  of  their  growth,  you  will  learn  that  the  plumule  is  at 
the  bottom  of  a  short  tube  formed  by  the  united  petioles  of 
the  cotyledons.     Sometimes  the  plumule  breaks  out  through

Xi 


the  side  of  this  tube  below  the  cotyledons,  instead  of 
bursting  through  between  them. 

Do  not  fail  to  see  for  yourself  how  squash 
embryos  pry  open  their  tongh  coats.  Soon  after  the 
sprout  has  gained  a  foothold  in  the  soil,  a  little  knob 
grows  on  the  side  of  the  radicle  so  as  to  split  more 
widely  open  the  £oint  of  the  seed  coat,  as  s^own  in  Fig.  c. 
Then  the  radicle  stem  between  the  knob  and  the  cotyledons, 
by  growing,  pries  the  seed  still  wider  open,  as  seen  at  6  below. 
Finally,  by  continued  growth,  the  cotyledons  are  pulled  out 
of  the  seed  coat  and  upward  to  the  surface  of  the  ground, 
where  they  expand,  and  become  pretty  good  leaves.  Seeds 
planted  edgewise,  which  of  course  could  rarely  happen  in  nature,  can  not 
tbus  free  themselves  of  their  seed  coats,  and  it  has  been  proved  by  a 
French  botanist  (M.  Flahault)  that  seeds  which  come  up  with  their  coats 
on  do  not  thrive.  The  seed  at  b  in  the  figure  was  first  planted  the  other 
side  up.  It  was  turned  over  when  the  knob  on  the  right  had  begun  to  open 
the  seed.  The  radicle,  which  then  pointed  directly  upward,  gradually 
straightened,  bent  downward,  and  finally  the  second  knob  grew,  by  the 
help  of  which  the  seed  leaves  were  in  a  fair  way  to  get  out  when  the  draw- 
ing was  made.  Some  native  California  plants  get 
out  of  their  coats  in  a  similar  manner. 

Germination  of  Albuminous  Seeds. 
You  Iiave  observed  that  when  seeds  without  al- 
buinen  send  their  cotyledons  above  ground,  the 
seed  coats  are  usually  left  behind,  but  the  albu- 
minous seeds  named  in  paragraph  5  retain  their 
seed  coats  often  for  several  days  after  they  come 
up.  Examine  the  coats  after  they  are  thrown  off, 
and  you  will  find  none  of  the  albumen  which 
formed  the  larger  part  of  their  contents  before 
germination.  The  enlarged  cotyledons  tell  what 
has  become  of  it,  and  it  is  now  plain  why  the 
coats  were  retained.

You  must  have  wondered  why  the  cotyledons  of  a  bean,  which 
never  become  leaf-like,  should  appear  above  ground.  It  is  equally  strange 
that  the  albuminous  seeds  of  the  peony  should  behave  in  the  reverse 
way.  As  shown  in  the  cut  (a  and  b),  the  embryo  is  very  email.  In 
germination  the  plumule  comes  up  while  the  cotyledons  become  decidedly 
leaf-like,  and  fill  the  shell  which  has  been  emptied  of  its  albumen  to  feed 
them  and  the  plumule.  These  thin,  veiny  seed  leaves  could  certainly  do 
better  work  above  ground  than  those  of  most  lupines,  yet  they  never  come 
up.  There  is  another  curious  thing  about  the  growth  of  peony  seeds, 
which  you  may  try  to  discover. 

When  the  buckwheat  and  cotton  seeds  have  begun  to  sprout, 
you  can  study  their  embryos.  Note  how  the  thin,  broad  cotyledons  of 
the  former  are  folded  once  and  rolled  up  with  a  layer  of  snow-white 
starch;  and  how  the  speckled  seed  leaves  of  the  latter  are  folded  along 
the  center,  then  outwardly  back,  and  finally  crumpled  endwise  to  make 
them  fit  coats  too  short  for  them.  Maple  seeds  have  curiously  crjmpled 
and  folded  cotyledons.  Indeed,  all  seeds  have  interesting  lessons  to 
teach  us.

their  embryos  in  germination,  but  they 
are  readily  enough  distinguished  from 
dicotyledons.  The  downward  growing 
sprouts  are  several  instead  of  one,  and 
the  upward  growing  sprout  is  like  a 
rolled  grass  leaf  (Figs.  15  to  17).  By 
tasting  of  the  growing  seeds  you  can 
discover  what  the  starchy  albumen  is 
changed  to  before  it  is  fit  food  for  the 
young  plant.  It  must  be  remembered 
that  only  the  grass-like  monoctyledons 
grow  as  here  represented.  If  possible,

sort  of  sleeping  state  from  which  it  may  be  aroused  to  activity  by  moist- 
ure and  warmth.  It  will  be  evident  that  the  radicle  is  a  stem;  that 
the  cotyledons  correspond  to  leaves,  and  that  the  plumule  is  a  bud 
from  which  is  to  grow  all  the  above-ground  portion  of  the  plant.  Ee- 
member,  that  if  these,  or  any  other  statements  concerning  the  structure

what  you  have  yourself  observed,  they  are  useless  to  you,  except  as  guides 
pointing  to  what  you  are  to  find.  To  memorize  these  statements  of  facts 
is  to  secure  the  husks,  not  the  kernels,  of  knowledge.  Plants  themselves 
must  teach  you  how  they  grow.  The  book  can  only  show  you  how  to 
question  them  and  how  to  interpret  their  answers.  Do  not  fail  to  care- 
fully compare  the  results  of  all  your  experiments;  for  in  this  way  you 
can  decide  what  are  general  or  usual  facts,  and  what  are  exceptional. 
The  latter  should  be  closely  investigated,  since  it  is  probable  that  there 
is  a  reason  for  all  unusual  as  well  as  usual  behavior  of  plants.

SECTION  2.— THE  STRUCTURE  OF  PLANTS. 

Steins.  While  awaiting  the  development  of  germs  in  your  experi- 
mental garden,  you  can  study  plants  which  have  already  reached  maturity 
in  wild  gardens.  Go  out  and  dig  up  the  first  plant — not  too  large — that 
you  find  in  blossom.  I  will  suppose  that  you  have  found  the  very  com- 
mon Filaria  (also  called  Pin-clover;  and  children  call  the  curious  seeds 
with  twisted  tails,  clocks).  Its  parts  are  Roots,  Stem,  Leaves,  and  Flowers. 
(Some  time,  if  you  continue  studying  Botany,  it  will  be  proved  to  you 
that  flowers  are  forms  of  stems,  or  stem-branches.) 

Crush  the  stem.  It  is  made  up  of  stringy  fibers  and  a  soft  sub- 
stance filled  with  juice.  The  former  is  generally  called  Fibrous  Tissue 
or  Wood ;  the  latter,  'Cellular  Tissue.  The  lower  part  of  the  stem  and 
the  upper  part  of  the  root — the  older  portions  of  the  plant — contain 
more  wood  than  the  branches  and  the  rootlets,  while  the  leaves  have  only 
net-like  skeletons  of  wood.  It  would  be  interesting  to  study  these  tissues 
with  the  aid  of  a  microscope,  and  thus  become  acquainted  with  the  inner- 
most structure  of  plants;  but  for  the  present  it  will  be  sufficient  if  you 
can  distinguish,  in  a  general  way,  wood  from  cellular  tissue. 

Cut  the  stem  squarely  across  near  the  upper  end,  and  from  one 
piece  take  a  thin  slice.  Stick  this  on  a  pin  and  hold  it  up  to  the  light. 
It  is  nearly  transparent,  except  a  green  ring  of  skin  outside  and  a  ring 
of  white  dots  inside.  The  latter  are  cut  ends  of  woody  fibers  which  run 
lengthwise  of  the  stem.  Make  a  similar  section  of  the  lower  part  of  the 
stem  and  you  will  find  a  continuous  ring  in  place  of  the  dots,  showing 
that  in  the  older  part  the  fibers  have  become  so  numerous  as  to  form  a 
hollow  cylinder  of  wood.  The  inclosed  cellular  tissue  is  called  the  Pith. 

Rsogens  and  Endogens.  If  the  stem  lives  year  after  year  there  will 
be  added  successive  layers  of  wood  outside  of  the  first  one.  Such  stems 
are  woody,  and  if  they  grow  many  years  become  Bushes,  /Shrubs,  or  Frees. 
Plants  that  grow  in  this  way  are  called  Exogens.  Examine  Asparagus, 
Soap-root,  Iris,  or  any  Lily  and  you  will  find  the  wood  fibers  scattered 
irregularly  through  the  stems.  These  plants  are  Endogens.  All  our  native 


INTRODUCTORY    LESSONS. 


trees  and  most  other  plants  are  exogens.     Palm-trees,  Century-plants, 
grasses,  and  the  "small  grains,"  are  endogens. 

Herbs  are  plants  whose  stems  die,  at  least  to  the  ground,  after 
they  have  blossomed  ana  matured  fruit.  These  are  Annuals  when  their 
lives  are  limited  to  one  season;  Biennials  when  they  die  the  second  year 
— not  producing  fruit  the  first  year;  Perennials  when  they  live  on  year 
after  year,  their  stems  dying  annually  down  to  the  ground.  The  under- 
ground portions  of  such  stems  are  called — 

Eootstocks.  This  name  applies  more  particularly  to  such  stems  as 
grow  nearly  horizontally  under  ground,  or  become  thick  and  fleshy  with 
nutritious  matter,  which  enables  the  plant  to  make  rapid  first  growths 
each  year.  A  rootstock  can  usually  be  distinguished  from  a  true  root 
by  its  bearing  buds. 

Bulbs  are  formed  by  a  peculiar  bud  growth  in  which  the  leaves  or 
tbeir  bases  become  very  thick  and  fleshy,  with  a  stpre  of  nourishment, 
while  the  stem  grows  in  diameter,  but  scarcely  at  all  in  length. 

Coated  or  Tanicated  Bulbs  are  those  in  which  the  leaves  form  a 
succession  of  envelopes,  as  in  the  onion.  If  the  leaves  or  leaf-bases  are 
narrow,  as  in  the  lily,  the  bulb  is  Scaly. 

Corms  resemble  bulbs,  but  are  solid,  and  have  more  the  nature  of 
Tubers,  which  are  the  thickened  ends  of  slender,  branching,  under- 
ground stems,  as  potatoes,  ground  artichokes,  etc. 

Leaves.  Collect  the  leafy  stems  of  many  kinds  of  plants.  Ob- 
serve the  arrangement  of  the  leaves  on  the  stems.  A  few  like  Erodium 
(Filaria),  the  Catchfly,  Pink,  Fuchsia,  Mint,  etc.,  have  Opposite  leaves. 
Possibly  you  may  find  a  Collinsia,  or  stem  of  Cleavers,  with  the  leaves  in 
Whorls  of  three  or  more.  Most  plants  have  Alternate  leaves.  You  will 
find  some  plants  like  Plantain,  with  a  bunch  of  leaves  growing  from  the 
ground,  but  no  leafy  stems.  Such  leaves  come  from  rootstocks,  and  are 
said  to  be  Radical.  Plantain,  Dodecatheon,  Primrose,  etc.  have  the  leaves 
all  radical.  Many  perennial  herbs  have  radical  leaves,  as  well  as  ordi- 
nary stem  leaves,  and  these  usually  differ  more  or  less  from  the  stem 
leaves. 

Observe  that  stems  and  branches  end  in  buds  or  flowers,  and  that 


XVI 


INTRODUCTORY    LESSONS. 


there  is  usually  a  bud,  or  branch,  or  a  flower  at  the  base  of  a  leaf  be- 
tween it  and  the  stem  from  which  it  grows. 

Buds  and  flowers  at  the  ends  of  stems  or  branches,  are  Terminal  ; 
when  between  the  stems  and  leaves,  Axillary. 

Examine  the  leaf  of  'a  Violet  or  Pansy.  You  can  readily  distin- 
guish three  parts:  A  broad  Blade  ;  a  stem  or  Petiole,  and  a  pair  of  appen- 
dages at  the  base  of  the  petiole  called  Stipules.  The  latter  in  the  Pansy 
are  leaf-like.  Sometimes  they  are  mere  scales,  and  frequently  there  are 
none  at  all.  The  petiole  may  be  wanting,  also;  the  leaf  is  then  said  to 
be  Sessile.  Leaves  with  but  one  blade  are — 

Simple  Leaves.  The  illustrations  (Figures  18  to  32)  show  the 
principal  forms  of  simple  leaves  or  leaflets  of  compound  leaves.  Care- 
fully compare  the  blades  of  your  leaves  with  these  shapes.  If  the  leaf 
in  hand  does  not  correspond  with  any  of  the  figures,  you  may  describe  it 
by  combining  the  descriptive  words,  or  by  adding  a  word.  A  leaf,  for 
example,  too  broad  to  be  lanceolate,  and  narrower  than  ovate,  if  about 
half  way  between  the  two  forms,  is  Ovate-lanceolate  or  Lance-ovate;  the 
first,  if  nearer  ovate;  the  latter,  if  nearer  lanceolate.  Or,  if  merely  a  lit- 
tle broader  than  lanceolate,  we  may  say  it  is  Broadly- lanceolate  ;  when  more 
slender,  Narrowly-lanceolate  ;  if  slender  and  nearly  as  broad  in  the  middle 
as  nearer  the  base,  it  is  Linear-lanceolate,  etc.  So,  too,  there  are  interme-

base  of  the  leaf.  Fig.  40  represents  a  pinnately  lobed  leaf;  Fig.  43, 
palmately  lobed.  When  leaves  are  deeply  lobed,  as  in  Figures  41  and  44, 
they  are  said  to  be  Parted.  Divided  leaves  are  cut  quite  to  the  midrib  if 
piimately  divided,  or  to  the  end  of  the  petiole  when  palrnately  divided. 
Cleft  leaves  have  the  sinuses  between  the  lobes  sharp  as  in  Fig.  38.  •  When 
leaves  are  pinnately  cleft  about  half  way  to  the  midrib  they  are  said  to  be 
'Pinnatifid.  If  the  lobes  are  pinnatifid  it  is  described  as  Bipinnatifid.  It 
is  common  to  give  the  number  of  lobes  in  the  descriptive  phrase,  as  pin- 
nately nine-lobed  (Fig.  40);  pinnately  eleven-parted  (Fig.  41);  palmately 
five-lobed  (Fig.  43);  palmately  five-parted  (Fig.  44). 

Compound  Leaves  have  distinctly  separate  leaflets  usually  jointed 
to  a  common  petiole,  just  as  simple  leaves  are  jointed  to  the  stem.  A  leaf 
is  Pinnate,  when  the  leaflets  grow 
along  opposite  sides  of  the  petiole 
(Fig.  42);  Palmate,  if  they  all  grow 
from  the  end  of  the  petiole  (Fig. 
46).  Fig.  45  represents  a  pinnately 
3-fuliolale  leaf;  Fig.  46,  palmately 
3-foliotate.  When  there  is  no  odd 
leaflet  at  the  end  the  leaf  is  ab- 
ruptly pinnate.  Leaves  may  be 
twice,  thrice,  etc.,  compound,  that 
is,  the  leaflets  may  be  compound 
as  in  some  acacias. 

Bracts  are  leaves  among  flow-

resemble  nets.     Examine  the  leaves  of  Iris,  Calla,  or  any  that  are  grass- 
like,  and  you  will  see  why  they  are  called  Parallel-veined. 

Netted-veined  leaves  grow  on  'Exogenous  stems.  Parallel-reined  leaves 
grow  on  Endogenous  stems.  The  former  belong  to  plants  which  grow  from 
Dicotyledonous  seeds;  the  latter  to  plants  from  Monocotyledonous  seeds. 

Flowers.  Get  a  bunch  of  Mustard  flowers — Wall-flowers,  single 
Stock,  or  Radish  flowers  will  do  as  well.  Pluck  a  single  blossom  and 
note  these  facts:  The  most  conspicuous  part  consists  of  four  yellow 
leaves;  outside  of  these  are  four  smaller  greenish  yellow  leaves  in  pairs 
not  quite  alike.  The  latter  are  Sepals,  and  together  form  the  Calyx  ;  the 
former  are  Petals,  and  together  form  the  Corolla.  Pull  off  the  sepals, 
observing  that  they  alternate  with  the  petals.  Next  remove  the  petals. 
The  broad  part  of  each  petal  is  called  the  blade,  the  narrow  part,  the  claw 
(corresponding  to  the  petiole  of  an  ordinary  leaf).  Inside  of  the  petals 
you  find  six  yellow-headed  bodies  with  white  stems,  two  of  which  are 
shorter  than  the  remaining  four.  These  are  the  Stamens.  Their  stems 
are  Filaments  ;  the  yellow  heads  are  Anthers,  and  the  yellow  powder  which 
they  contain  is  Pollen.  In  the  center  of  the  flower  is  a  club-shaped  body 
called  the  Pistil.  This  is  the  young  seed-pod,  and  by  splitting  it  open 
you  may  see  the  minute  Ovules,  which  are  the  beginnings  of  seed.  The 
part  containing  the  ovules  is  the  Ovary  ;  the  naked  upper  end  of  the  pis- 
til is  the  Stigma^  and  the  part  connecting  the  stigma  with  the  ovary  is  the 
Style.  The  end  of  the  stem 
upon  which  the  parts  of  the 
flower  grow  is  the  Receptacle, 
and  the  stem  is  called  a  Pe- 
duncle. Fig.  47  will  assist 
you  in  learning  these  names. 

A  Complete  Flower 
must  have  calyx,  corolla, 
stamens  and  pistils;  but,  since 
the  office  of  a  flower  is  to  pro- 
duce seeds,  and  these  grow 
from  ovules,  which  pollen  has 
reached  by  way  of  the  stigma,

INTRODUCTORY    LESSON8. 


A  Perfect  Flower  may  consist  of  pistils  and  stamens  only,  and  of 
these  the  styles  and  filaments  are  not  essential. 

Cohesion  of  Floral  jjfcgans.  When  sepals  cohere  or  grow  fast  to 
each  otlap  (Figs.  48- 
51)  the  calyx  is  Gamo- 
sepalous.  So,  also, 
the  corolla  may  be 
Gamopetalous.  When 
stamens  cohere  they 
are  Monadefphous  if 
in  one  set,  Diadel- 
phous  if  in  two  sets 
(usually  9  and  1),  etc.

If  the  flower  has  a  limb  (border)  dis- 
tinct from  the  tube,  these  terms  apply  to 
the  limb. 

Adhesion  of  Floral  Organs.  The 
calyx  may  grow  fast  to  the  ovary  (Fig.  51), 
then  it  is  said  to  be  Superior  (ovary  in- 
ferior). The  corolla  and  stamens  fre- 
quently grow  on  the  calyx,  as  in  Fuch- 
sia, Strawberry,  etc.;  then  they  are  said 


XX11

to  be  Perigynous ;  or  the  stamens  may  grow  on  the  corolla  (f^ig.  50)  as 
in  most  gamopetalous  flowers,  and  in  Eschscholtzia  (Fig.  49).  In  the 
Orchis  Family  the  stamens  grow  on  the  pistil. 

Irregular  Flowers  are  those  in  which  parts  of  the  same   kind  are 
unlike  in  form  or  size. 

Inflorescence.  The  forms  of  flower-clusters  are  almost  as  various 
as  the  shapes  of  the  flowers,  but  they 
may  all  be  referred  to  two  plans,  viz. : 
Terminal  and  Axillary.  The  Raceme 
(Fig.  52)  is  a  simple  form  of  axillary 
inflorescence  in  which  the  leaves  are 
reduced  to  bracts.  If  the  flowers  are 
sessile  (without  pedicels)  the  raceme 
becomes  a  Spike  (Fig.  53).  If  the 
older  flowers  are  raised  on  long  pedi- 
cels the  flat-topped  cluster  is  called  a 
Corymb  (Fig.  55).  In  an  Umbel  the 
pedicels  all  grow  from  the  end  of  the

peduncle  (Fig.  56).  If  these  are 
very  short  or  obsolete  a  Head  is 
formed.  A  Panicle  is  a  loose  com- 
pound raceme.  A  Thyr&e  is  a  dense 
panicle.  Fig.  54  represents  a  Cyme, 
the  type  of  terminal  inflorescence.  A 
many-flowered  cyme  is  a  Fascicle  ;  more 
densely  flowered,  a  Glomerule.  Cymes 
and  Fascicles  resemble  Corymbs;  but 
in  the  former,  the  central  flowers  are 
the  older,  while  in  the  latter,  the  younger  flowers  or  buds  occupy  the 
center.  Glomerules  differ  from  heads  in  the  same  way. 

The  woodland  flowers  Trillium  and  Anemone  furnish  examples  of 
the  simplest  form  of  Terminal  Inflorescence.  Their  simple  stems  bear 
each  one  flower  at  the  top.  Often  flowers  seem  to  be  axillary  when  the 
plan  of  inflorescence  is  terminal.  Fig.  57  illustrates  a  case  of  this  kind-

Suppose  that  one  of  the  branches  in 
Fig.  54  had  failed  to  grow.  The  first 
flower  would  then  appear  to  be  axil- 
lary. In  the  plant  represented  by 
Fig.  57,  two  of  each  set  of  three 
axillary  buds  usually  remain  dormant. 
Their  growth  would  complete  a  Tri- 
chotomous  Cyme.  Fig.  54  represents  a 
Dichotomous  Cyme.  Imagine  the  plant 
shown  in  Fig.  57  to  continue  branch- 
ing, the  stem  to  be  shortened  so  as  to 
bring  the  flowers  close  together,  and 
the  leaves  to  become  obsolete.  A 
bunch  of  flowers,  having  the  appear- 
ance of  a  one-sided  raceme,  would  be 
formed.  Let  the  flowers  become  ses- 
sile, and  we  would  have  a  false  spike. 
Such  mimic  racemes  and  spikes  are 
usually  coiled  as  shown  in  Fig.  64. 

The  common  Auagallis,  whose 
pretty  salmon-colored  flowers  appear  in 
the  axils  of  the  opposite  leaves  (Fig.  58), 
is  an  illustration  of  simple  Axillary  In- 
florescence. Imagine  the  leaves  reduced 
to  bracts,  and  the  stem  shortened.  The 
fruit,  flowers,  and  buds  would  then  form 
a  Bracteate  Raceme.  Let  the  bracts  be- 
come wanting,  and  we  would  have  a  naked 
or  Bractless  Raceme,  similar  to  the  one 
shown  in  Fig.  59.  This  raceme  wants 
only  a  slight  lengthening  of  the  lower 
pedicels  to  become  a  Corymb.  Indeed,  it 
might  be  called  a  Corymbose  Raceme. 
Fig.  60  represents  a  naked  raceme,  in 
which  only  one  or  two  flowers  are  in

bloom  at  a  time.    A  dense  Spikfy 
bearing  a  ring  of  flowers  be- 
tween  growing   ovaries  below 
and  expanding  buds  above,  is 
shown  in  Fig.  61.     The  coiled  spike  (Fig.  64)  is 
really  a  kind  of  cyme,  as  has  been  shown.     This 
Scorpioid  Inflorescence  is   characteristic  of   two 
families  of   plants,  represented   by  many  plants  on 
this  coast.     Mosquito  Bills  (Fig.  62)  grow  in  Brac- 
teale  Umbeh.     The  Head  or  Capitate  cluster  (Fig.  63) 
is  like  an  umbel,  only  the  pedicels  are  mostly  very 
short.     When  the  flowers    are  numerous,  the  head 
becomes   Globose.      The   true   clovers  have   capitate 
flowers.     When  the  pedicels  in  a  raceme  branch  so 
as  to  bear  two  or  more   flowers  each,  a   Compound 
Raceme  is  formed.      So  in   like  manner  Compound 
Umbels t  Spikes,  and  Corymbs  may  be  formed.     These 
flower  bunches,  cymes,  racemes,  etc.,  may  be  at  the  ends  of 
main  stems  or  branches,  or  in  the  axils  of  leaves,  or  replace 
single  flowers  in  any  kind  of  inflorescence. 

The  Calyx,  as  we  have  already  learned,  is  composed 
of  leaves  called  Sepals,  which,  though  different  from  ordinary 
leaves  in  shape,  are  usually  green.  When  the  sepals  are  separate,  the 
flower  is  Polysepalous.  Sepals  united  partly  or  wholly  form  a  Gqmo- 
sepalous  calyx.  If  the  sepals  drop  off*  when  the  flower  opens,  as  shown 
on  p.  20a,  they  are  Caducous.  If  they  fall  with  the  petals,  or  before  the 
fruit  is  ripe,  they  are  Deciduous.  A  Persistent  Calyx  remains  until  the

fruit  ripens  (Fig.  65).  A  colored 
calyx — i.  e.,  not  green — is  said 
to  be  Petaloid.  Flowers  with- 
out petals  and  those  of  the  Lily 
Family  usually  have  petaloid 
sepals  (Figs.  66,  70,  71). 

The  Corolla  is  Polypet- 
alous  when  the  petals  are  free 
from  each  other  (see  Figs.  66, 
68,  69,  73).  In  Gamopetalous 
corollas  there  are  all  degrees  of 
cohesion  from  the  complete 
union  (Fig.  67)  of  the  Entire 
limb  to  the  almost  free  petals 
of  a  Divided  corolla  (Fig.  58). 
Petals  often  grow  upon  the  calyx 
(Fig.  68).  Corollas  are  Regular 
(Figs.  67,  69)  or  Irregular  (Fig. 
66,  and  Fig.  58,  p.  3.  See  also 
the  figures  on  p.  11  and  p.  88b). 
Common  forms  .of  regular  co- 
rollas are  Rotate  (Fig.  58),  Salver- 
form  (Fig.  64),  Funnel-form 


(Fig.  67),  and  Campanulate  or  Bell-shaped  when  the  tube  expands  suddenly 
at  the  base  to  a  width  nearly  equal  to  that  of  the  summit  and  about  equal

to  a  third  of  the  length.  Irregular  flowers  are  frequently 
Bilabiate  or  Two-lipped,  as  shown  in  the  figures  a  and  c  on 
p.  11,  and  the  figures  on  p.  88b.  When  the  tube  of  a  corolla 
is  slender,  and  the  regular  or  irregular  limb  is  small  or  want- 
ing, the  flower  is  said  to  be  Tubular.  The  term  Perianth  is 
used  to  designate  the  calyx  and  corolla  taken  together.  It  is 
mostly  used  in  describing  endogenous  flowers  (Figs.  70,  71). 
Stamens  may  grow  upon  the  receptacle  (Hypogynous, 
Fig.  69),  upon  the  calyx  (Perigynous,  Fig.  68),  upon  the 
corolla  (Fig.  67),  or  upon  the  pistil.  Stamens  are  often 
united  by  their  filaments  so  as  to  form  tubes  (Fig.  74)  or 
bundles;  or  the  anthers  are  joined,  as  in  the  Sunflower  or 
Thistle.  Sometimes  there  are  two  kinds  of  stamens  in  the  same  flower 
(Fig.  68).  Staminodia  are  antherless  or  abortive  stamens  (see  longer  sta- 
mens in  Fig.  e,  p.  8).  Anthers  usually  consist  of  two  cells,  which  are 
filled  with  Pollen.  If  the  upper  end  of  the  filament  lies  exactly  between 
the  anther  cells,  the  anther  is  Innate.  An  Adnate  anther  is  attached  by 
one  side  to  the  filament  (Figs.  67,  68).  A  Versatile  anther  is  attached  be- 
tween its  ends  by  one  side  to  the  tip  of  the  filament  (Figs.  71,  72).  The 
pollen  usually  escapes  from  slits  in  one  side  of  the  anther,  as  shown  in 
Fig.  69.  This  side,  which  in  an  adnate  or  versatile  anther,  is  opposite 
the  filament,  is  called  the  face  of  the  anther.  When  the  anther  faces 


INTRODUCTORY    LESSONS.  XXV11 

the  pistil,  it  is  Introrse  (Figs.  68,  71,  72,  73);  and  when  it  faces  away 
from  the  pistil,  it  is  Extrorse  (Fig.  69). 

The  Pistil  grows  upou  tbe  receptacle,  or  upon  a  stem  arising 
from  it,  called  a  Stipe  (Fig.  71).  In  a  few  orders  there  are  several  or 
many  pistils  in  each  flower.  Usually  there  is  but  one,  formed  of  several 
simple  pistils  (carpels)  united  more  or  less  closely.  As  in  the  other  floral 
organs,  there  are  all  degrees  of  cohesion,  from  a  slight  union  of  the 
bases  of  the  ovaries — rarely  of  the  stigmas  only — to  such  completeness 
as  leaves  no  trace  of  lobes  in  the  stigma  (see  Fig.  on  p.  5).  Often  the 
free  styles  tell  how  many  carpels  compose  the  pistil  (Fig.  69).  Generally 
the  stigmas  are  divided  or  lobed  (Fig.  68).  These  marks  wanting  a  cross 
section  of  the  ovary,  or,  better  still,  of  the  partly  grown  fruit,  will  usu- 
ally show  a  cell  for  each  carpel  (see  the  right-hand  figure,  p.  88b).  If 
the  ovules  (or  young  seeds)  are  in  the  center  or  grow  on  more  than  one 
side  of  the  ovary  (or  pod),  the  pistil  is  compound.  A  simple  pistil  is 
generally  plainly  one-sided.  A  symmetrical  pistil  is  compound. 

Inferior  Ovaries.  When  the  calyx  adheres  to  the  ovary,  so  as 
to  form,  after  the  ovary  has  matured,  the  outer  part  of  the  fruit,  it  is 
said  to  he  superior,  because  the  apparent  catyx,  its  lobes,  or  cup,  seem 
to  grow  upon  the  ovary.  For  the  same  reason  the  ovary  is  said  to  be  in- 
ferior (Figs.  68,  72).  There  are  all  degrees  of  adhesion,  from  the  slight 
union  at  the  base,  as  seen  in  Whipplea  (Fig.  73),  to  the  remarkable  ex- 
treme exhibited  in  the  plant  figured  on  p.  5,  in  which  not  only  the  ovary, 
but  several  inches  of  the  style,  is  adherent  to  the  calyx.  When  the 
adhesion  is  only  partial,  it  can  be  shown  by  cutting  the  flower  vertically, 
as  represented  in  Fig.  73. 

The  Fruit  is  the  ripened  ovary  (or  set  of  ovaries),  and  all  that 
directly  belongs  to  it.  A  dry  fruit  which  opens  in  any  way  to  let  out  the 
seeds  is  called  a  Pod,  A  pod  formed  by  the  growth  of  a  simple  pistil 
(one-carpeled)  is  called  a  Follicle  when  it  splits  only  along  the  side  which 
bears  the  seeds.  A  Legume  splits  down  both  edges.  Pods  formed  of 
several  carpels  are  called  Capsules.  Akenes  are  dry,  indehiscent,  seed- 
like  fruits,  containing  but  one  seed.  Utricles  are  distinguished  from 
akenes  by  their  thin  coats,  which  are  too  large  for  the  inclosed  seed.

IMTBODDCTOEY    LESSONS. 


There  are  many  other  names  applied  to 
fruits,  which  it  is  not  necessary  to  define 
here. 

The  Growth  of  Ovules.     You  can 

not  study  the  development  of  ovules  from  the 
beginning,  without  the  help  of  a  compound 
microscope,  but  you  can  easily  observe  all 
stages  of  growth,  from  a  tiny  green  speck 
to  the  full-grown  embryo.  Most  seeds  are 
nearly  full  grown  in  appearance  before  the 
embryo  is  more  than  fairly  visible  to  the 
naked  eye.  The  seed  coat,  filled  with  a 
syrupy  or  milky,  usually  sweet,  liquid,  ap- 
pears to  constitute  the  very  young  seed. 
With  a  sharp  knife  cut  in  halves  a  great 
many  green  peas,  in  size  from  half  grown 
upward.  You  will  surely  find  in  some  of 
them  tiny  green  embryos,  and  you  may  get  specimens  from  the  size  of  a 
pin's  head  up  to  those  which  tightly  fill  the  seed  coat.  In  Fig.  75,  at  the 
top,  is  seen — magnified  two  diameters — the  young  seed  of  a  lupine,  cut  so 
as  to  show  the  young  embryo  lying  in  one  end.  In  the  same  figure  is 
represented  a  radish  pod,  laid  open  so  as  to  show  three  of  the  seeds,  two 
of  which  exhibit  their  partly  grown  embryos.*  Below,  at  b,  is  one  of 
these  magnified,  and  at  a  an  older  one,  also  magnified.  The  grown  em- 
bryo completely  fills  the  seed.  Observe  the  positions  of  the  embryos  in 
relation  to  the  stems  of  the  seeds  and  the  stems  of  the  pods.  The  lower 
seed  in  the  radish  is  fastened  to  the  lower  side  of  the  pod,  the  middle 
seed  grows  to  the  upper  side.  The  cotyledons  increase  much  more  in 
size  than  the  radicle.  The  embryo  evidently  grows,  in  part  at  least,  by 
absorbing  the  liquid  around  it.  Suppose  the  embryo  of  the  lupine  to  quit 
growing  at  the  size  represented  in  the  figure,  and  that  the  liquid  around 
it  thickens  until  it  becomes  solid.  Would  not  the  seed  thus  formed  be 
albuminous  ? 


*  These  are  cut  in  two.    The  embryo  may  be  seen  through  the  seed-coat,  as  represented  at  6,  by  hold 
ing  it  up  to  the  light.    Half  of  the  seed-coat  is  removed  from  a. 


SYSTEMATIC  BOTANY. 


NAMES   OF  PLANTS:    CLASSIFICATION. 

In  a  general  way  we  designate  the  objects  around  us  by  single 
names.  We  speak  of  a  stone,  a  wolf,  or  a  pine;  but  to  distinguish  the 
kinds  we  naturally  use  two  names,  as  lime  stone,  sand  stone;  grey  wolf, 
prairie  wolf;  nut  pine,  yellow  pine,  etc.  This  is  one  step  in  classifica- 
tion, and  the  only  one  commonly  taken.  This  natural  plan  of  double 
names  was  adopted  by  the  great  naturalist,  Linnaeus,  who  gave  names  to 
most  European  plants,  as  well  as  to  many  of  this  continent.  He  wisely 
gave  the  Latin  form  to  his  names,  since  that  language  (being  the  base  of 
most  languages  spoken  in  civilized  countries)  is  the  natural  source  of  cos- 
mopolitan names — those  truly  common  to  all  people.  Botanical  names, 
then,  differ  from  so-called  common  names  principally  in  form,  and  they 
have  these  decided  advantages:  they  more  exactly  represent  the  rela- 
tions between  kinds  of  plants,  and  they  are  names  that  are  common  to 
people  of  all  languages.  In  short,  they  are  the  true  common  names. 

It  is  not  true  that  botanical  names  are  harder  than  local  names.  The  most  com- 
mon of  our  ornamental  plants  are  well  known  by  their  scientific  names.  No  one  thinks 
of  calling  the  following  botanical  names  hard :  Geranium;  Aster;  Verbena;  Petunia;  Por. 
tulaca;  Crocus;  Phlox;  Fuchsia;  Iris;  Magnolia;  Oxalis;  Azalea;  Dahlia;  Lobelia;  Ar- 
nica, etc.  Most  people  talk  familiarly  of  Camellias,  Callas,  Begonias,  Acacias;  etc.: 
while  cur  beautiful  California  plants,  Clarkia,  Collinsia,  Eschscholtzia  Nemophila,  etc., 
are  well  known  by  their  proper  names — at  least,  in  other  countries. 

Generic  Names  correspond  to  the  second  parts  of  the  compound  com- 
mon names,  as  oak,  pine,  rose,  etc.  Some  of  these  are  the  old  Greek  or 
Latin  names  of  the  plant.  Most  generic  names  are  either  derived  from 
Greek  or  Latin  words  descriptive  of  some  peculiarity  of  the  plant,  or  they 
are  commemorative  of  some  botanist,  as  Thysanocarpus,  from  Greek 
words  meaning  fringe  and  pod;  Kelloggia,  in  honor  of  Dr.  A.  Kellogg,  a 
veteran  botanist  of  this  coast.  Sometimes  genera  are  named  in  honor  of 
those  who  are  not  botanists,  as  Fremontia,  Hollisteria,  etc. 


2  SYSTEMATIC    BOTANY. 

Specific  Names  are  adjectives  corresponding  to  the  first  parts  of  com- 
mon names.  They  are  usually  descriptive  of  some  characteristic  of  the 
plant,  as  Gilia  liniftora,  Flax-flowered  Gilia.  Frequently  a  species  is 
named  for  the  discoverer,  as  Gilia  Bolanderi,  Bolander's  Gilia;  often  for  the 
country  where  it  vr*^  first  found,  or  where  it  abounds,  as  Ranunculus  Cali- 
fornicus,  California  Buttercup.  Sometimes  there  are  varieties  of  a  species 
as  TrifoUum  barbigerum,  Var.  Andrewsii,  Andrews1  Bearded-Clover. 

Orders  and  Classes.  Genera  are  grouped  in  Orders  or  Families, 
and  these  in  Classes.  There  are  two  classes  of  flowering  plants,  Exogens 
and  Endogens. 

ANALYSIS  OF  PLANTS. 

This  whole  matter  of  naming  and  classifying  can  be  well  under- 
stood only  after  you  have  analyzed  many  plants;  i.  e.,  you  must  have 
carefully  examined  them  part  by  part,  and  patiently  compared  their  pecul- 
iarities with  the  descriptions  in  the  Flora  until  you  have  determined 
their  names.  In  the  beginning  there  will  be  many  failures;  but  do  not 
allow  them  to  discourage  you,  for  each  victory  will  make  the  way  easier 
to  other  conquests. 

Choose  for  your  first  studies  plants  with  large  flowers.  Do  not 
attempt  to  determine  the  name  of  a  plant  unless  you  have  specimens 
which  show  the  kind  of  inflorescence  and  the  arrangement  of  the  leaves 
on  the  stem.  If  possible,  secure  specimens  of  the  fruit  and  the  roots. 
If  in  any  plant  you  cannot  readily  distinguish  the  parts  of  the  flower  and 
their  relations  to  each  other,  lay  it  aside  until  the  study  of  easier  plants 
has  given  you  more  skill. 

The  first  thing  to  be  determined  in  analyzing  a  plant  is  the  Ctass; 
i.  e.,  you  must  decide  whether  it  is  an  Exogen  or  an  Endogen.  You  have 
learned  in  the  preceding  lessons  how  the  seeds  and  stems  of  these  two 
Classes  of  Flowering  Plants  differ.  Usually,  however,  the  leaves  and 
flowers  sufficiently  distinguish  the  class.  In  our  plants,  if  the  leaves  are 
parallel-veined;  or,  if  the  parts  of  the  flower  are  in  threes  the  plant  is  an 
endogen.  In  other  words,  if  there  is  no  network  of  intersecting  fibers 
between  the  ribs  of  the  leaves  the  plant  is  an  endogen;  if  the  flower  has

three  sepals  and  three  petals  (i.  e.,  a  perianth  of  six  leaves  or  lobes),  three 
or  six  stamens  and  three  or  six  pistils  (generally  united  to  form  a  compound 
pistil  with  a  three  or  six-celled  ovary)  the  plant  is  an  endogen.  When 
the  leaves  are  netted-veined,  and  the  parts  of  the  flower  are  not  all  in 
threes,  the  plant  is  an  exogen. 

It  is  a  good  plan  to  write  out  a  description  of  a  plant  before 
attempting  to  ascertain  its  name.  The  parts  may  be  described  in  this 
order:  floots,  Stems,  Leaves,  Flowers,  Fruit. 

You  may  find  a  smooth  plant  bearing  a  loose  raceme  of  red  flowers, 
one  of  which  is  represented  in  Fig.  57.  The 
floral  leaves  are  all  colored,  but  there  are 
evidently  two  sets;  viz. :  a  calyx  of  5  sepals 
inclosing  a  corolla  of  4  petals.  The  parts  of 
the  flower,  then,  are  not  in  threes;  and,  since 
the  palinately  lobed  leaves  are  netted-veined 
the  plant  must  be  an  exogen.  Turning  to 
the  key,  we  proceed  as  follows : 

The  plant  must  belong  in  "  DIVISION  1,"  since  by  carefully  removing  the  sepals 
ami  petals  we  find  that  the  latter  are  separate  from  each  other.  It  must  be  found  under 
"A,"  for  there  are  many  stamens.  The  stamens  are  free  from  the  calyx  and  corolla,  i.  e., 
they  are  hypogynous;  so  we  read  the  next  line:  "  Pistils,  few  to  many  distinct  carpels, 
rarely  one."  Our  flower  has  three  distinct  carpels,  therefore  we  feel  sure  that  it  must 
be  sought  under  one  of  the  next  five  equal  lines  beginning  with  "Calyx."  As  the 
calyx  is  easily  shaken  off  from  the  older  flowers  we  decide  that  it  is  deciduous.  Tin; 
juice  is  colorless  also.  We  turn,  therefore,  to  RANCNCULACEA:,  p.  16.  The  description 
of  the  order  is  satisfactory.  The  key  to  the  genera  begins  with  the  heading  "  *Flow«r* 
regular."  Ours  is  not,  for  the  upper  sepal  is  unlike  the  others.  "  **Floicer*  irregular; 
colored  sepals  conspicuous,"  is  right.  We  now  choose  between  "  Upper  sepal  spurred,' 

and  « « Upper  sepal  hooded. "  Evidently  the  first 
is  right,  and  the  genus  is  Delphinium.  We  find 
that  the  generic  description  on  p.  18  fits  our 
plant.  The  last  species  being  the  only  one  with 
red  flowers,  we  decide  that  our  plant  is  Del- 
phinium nudicaule,  or  the  Naked-stemmed  Lark- 
spur. 

Tbe   order  Leguminosae,  or  the 
Pea  Family,  is  one  that  you  will  soon

learn,  since  its  characteristics  are  well  marked.  We  will  suppose  that 
you  have  before  you  a  very  common  blue-flowered  shrubby  plant  belong- 
ing to  that  order,  a  single  flower  of  which  is  shown  in  Fig.  58.  Knowing 
the  order,  you  turn  at  once  to  p.  38,  and  begin  to  use  the  key  to  the 
genera. 

Carefully  removing  all  the  petals,  the  stamens  and  pistil  appear  as  in  a,  Fig.  59. 
The  filaments  are  united  for  the  greater  part  of  their  length  into  a  tube  which  incloses 
the  ovary  as  a  sheath  does  a  knife.  Of  the  three  sections  in  the  key,  then,  it  is  evident 
that  the  second  is  to  be  taken.  Since  some  of  the  anthers  have  shed  their  pollen,  and 
others  have  not,  it  is  safe  to  say  they  are  of  two  kinds  —  a  bud  will  show  the  difference 
better  (b,  Fig.  59.)  Moreover  the  leaves  are  digitate,  and  have  more  than  three  leaflets 
We  therefore  conclude  that  the  third  genus  is  the  one.  Our  plant  is  slightly  shrubby, 
so  we  pass  over  the  first  heading  in  the  synopsis  of  species.  Of  the  second  and  third 
headings  the  last  seems  the  most  likely  to  lead  us  aright.  Our  flower  is  blue,  so  we  have 
to  choose  between  the  second  and  third  species.  The  words  "  Slightly  woody  at  the 
base,"  decide  us  in  favor  of  Lupinus  Douylasii,  though  we  should  examine  more  speci- 
mens before  being  quite  positive. 

Fig.  60  represents  a  flower  of  a  plant 
common  in  the  Redwood  forests.  Three  or 
more  of  the  dull-colored  flowers  grow  in  an 
umbel  on  a  very  short  scape  between  a  pair  of 
spreading  radical  leaves.  Since  the  leaves  have 
parallel  veins,  and  the  parts  of  the  flower  are 
in  threes,  we  must  use  the  Analytical  Key 
for  Endogens,  p.  13.  You  will  have  no  diffi- 
culty in  referring  the  plant  to  the  ORDER  LILIA- 
CEM.  To  make  the  analysis  of  a  plant  in  ^ 
large  order  easy,  the  genera  are  grouped  in  the  bursting  anther  ceils. 
three  Series.  Beading  the  characteristics  of  SERIES  I,  we  find  they  do 
not  correspond  with  those  of  our  plant,  which  has  no  floral  bracts,  which 
has  the  stamens  hypogynous  instead  of  perigynous,  the  anthers  extrorse 
instead  of  introrse,  etc.  Comparing  Series  II  with  Series  III,  we  decide 
that  our  plant  belongs  in  the  former,  since  the  perianth  is  not  persistent, 
and  the  flowers  are  not  in  racemes  or  panicles.  §  1,  in  Series  II  is  wrong, 
for  our  plant  has  no  leafy  stem.  Since  the  perianth  segments  of  our 
flower  are  dissimilar  we  try  §  3,  under  which  we  refer  our  plant  to  the

genus  Scoliopus.  Turning  to  the  description  of  the  only  species  de- 
scribed, we  find  it  satisfactory.  Upon  referring  to  the  Glossary  of 
Generic  and  Specific  Names  in  the  back  part  of  the  book,  we  find  why 
the  plant  was  named  Scoliopus  Bigelovii. 

This  picture  represents  part  of  a  plant  whose  yellow 
flowers  are  among  the  first  to  greet  the  new  year. 
It  is  shown  as  it  would  appear  if  cut  down  through 
the  center  after  removing  most  of  the  outer  leaves. 
The  leaves  and  flowers  all  grow  from  the  flat  summit 
of  a  thick  root-stock.  It  will  be  noticed  that  the 
buds  are  younger  as  the  center  is  approached.  Possi- 
bly you  have  tried  to  analyze  one  of  these  flowers. 
If  so.  you  probably  got  on  nicely  till  you  tried  to 
find  the  ovary.  I  hope  you  kept  searching  and  at 
last  felt  the  satisfaction  which  rewards  the  discoverer. 
However,  you  can  determine  the  name,  and  thus 
have  the  book  tell  you  where  the  ovary  is.  The 
poorest  eyes  can  see  that  the  leaves  are  all  radical; 
that  the  four  divisions  of  the  calyx  are  reflexed;  that 
four  broad  petals  and  eight  stamens  grow  upon  it; 
and  that  there  is  one  pistil  whose  slender  style  bears 
a  globose  stigma.  You  can  not  doubt  that  the  plant 
is  to  be  sought  under  B.,  in  Division  1,  but  you  are 
unable  to  say  whether  the  ovary  is  superior  or  not. 
In  such  a  case,  search  first  for  the  order  under  the 
head  ' '  OVARY  SUPERIOR;"  and,  if  not  satisfied 
there,  try  the  head  " OVARY  AND  FRUIT  INFERIOR." 
Since  there  is  but  one  pistil,  you  look  under  "  *  *  Pis- 
til only  one. "  The  plant  is  not  a  shrub,  so  you  next 
stop  at  "ff  Herbs.'"  The  first  division  under  this  is. 
the  only  one  admissible,  because  the  leaves  are  all 
radical.  But  in  no  case  under  this  head  is  the  num- 
ber of  stamens  eight.  We  therefore  try  the  sub- 
head "2.  OVARY  AND  FRUIT  INFERIOR,"  etc.  It  is 
evident  that  the  descriptive  line,  "Parts  of  the  flower 
mostly  in  4's,"  etc.,  is  the  only  one  that  fits  our 
plant,  so  we  turn  to  p.  59,  where  we  find  nothing  in 
the  description  of  the  order  Onagracese  to  rule  our 
plant  out.  The  lines  descriptive  of  the  genera  are 
unsuited  to  our  plant,  except  one,  which  refers  us  to  the  genus  (Enothera,  the  de-

scription  of  which  (p.  60)  is  satisfactory.  Our  plant  is  acaul<'.tsccnt  or  stemless;  therefore, 
according  to  the  book,  the  calyx  tube  is  filiform  (slender)  above  the  underground  ovary. 
This  being  verified  by  examination,  there  can  be  little  doubt  that  the  plant  is  (Enothern 
ovata.  You  now  see  that  the  flowers,  instead  of  growing  upon  scapes,  are  sessile  upon 
the  end  of  a  root-stock.  The  apparent  flower  stem  is  the  slender  calyx  tube  and  style 
consolidated.  When  you  plucked  the  flower,  the  ovary  was  left  under  the  ground.  No 
wonder  you  could  not  find  it.  Later  in  the  season  you  will  find  other  plants  belonging 
to  this  order;  then  the  figures  above  will  help  you. 

The  figure  at  the  right  above  represents  the  upper  part  of  a  plant  which  usually  grows 
in  moist  places.  The  white  flowers  have  four  separate  sepals;  four  petals;  six  stamens  in 
two  sets,  two  being  shorter  and  otherwise  different  from  the  other  four,  and  one  pistil.

These  characters  lead  you  in  the  key  to  the  order  Cruciferae,  but  it  is  not  easy  to  decide 
farther,  because  you  have  not  the  fruit.     Look  for  the  pods  a  few  weeks  later,  and  you 

will  find  them  long  and  flat,  as  represented  in  the 
figure  at  e  on  the  left.  You  can  then  determine 
the  name  of  the  plant.  The  seed  pods  here 
figured  will  help  you  in  determining  some  of  the 
plants  in  this  order. 

The  curious  flower  depicted  below  is  another 
early  bloomer.'  You  must  cut  the  flower  open 
and  study  it  carefully.  The  four— sometimes 
five— petals  are  joined  together,  and  bear  upon 
the  short  tube  the  four  stamens  which  hug  the 
pistil  tightly  and  form  a  beak  like  that  of  a  bird. 
The  ovary  does  not  adhere  to  the  calyx,  and  if  a 
seed  pod  is  partly  grown,  it  will  be  easy  to  see 
that  the  seeds  grow  upon  a  central  placenta. 
Turning  to  the  key  you  are  called  upon  to  de- 
cide whether  the  stamens  are  opposite  the  lobes 
of  the  corolla  or  not.  They  certainly  are  op- 
posite, so  the  order  Primulaceae  is  evidently 
where  our  plant  belongs.  The  pretty  little  for- 
eigner Anagallis  is  here  figured,  and  it  will  be

species  grouped  under  three  sub-genera  or  sections. 
Figures  a,  d,  and  e  illustrate  the  first,  c  the  sec- 
ond, and  b  the  third.  The  species  belonging  to 
the  first  section  are  arranged  under  two  heads 
marked  by  asterisks,  and  those  under  the  first  head 
are  under  subheads  marked  by  daggers.  Species  4 
and  5  closely  resemble  number  6,  which  is  put  un- 
der a  different  head,  because  it  has  six  true  or 
anther-bearing  stamens  instead  of  three  stamens 
and  three  staminodia.  Fig.  a  shows  that  three  of

notched  at  the  top  as  shown  in  the  figure.  The  species  in  §  Seubertia  resemble  the  first 
three  in  general  appearance,  but  the  stamens  and  pistils  are  very  different,  as  is  shown 
by  Fig.  c.  Observe  that  the  stamens  have  versatile  instead  of  basifixed  anthers;  and  the 
ovary  is  upon  a  stipe,  instead  of  being  sessile.  Douglas'  Brodioea,  of  Oregon,  is  like

The  middle  figure  on  the  next  page  represents  a  plant,  the  curious  cup-like  leaves  of 
which  must  have  attracted  your  attention.  The  leaf  cups  are  frequently  much  larger  than 
here  shown,  and  borne  upon  stems  a  foot  or  more  in  height.  Though  the  flowers  are  small,

you  readily  decide  that  the  sepals  are  two,  and 
that  there  are  five  petals  and  five  stamens.  The 
seed  pods  show  that  there  is  but  one  pistil,  and 
that  the  calyx  does  not  adhere  to  the  ovary;  that 
is,  the  ovary  is  superior.  Armed  with  this  in- 
formation, you  turn  to  the  key  where  you  search 
under  "B.  STAMENS  10  or  less."  Evidently  the 
correct  subheads  are:  "1.  Ovary,  or  ovaries,  supe- 
rior," etc.;  "*  *  Pistil  only  one;"  "  ft  Herb*;" 
"  £  Leaves  mostly  radical;"  ' '  Stamens  5,  opposite  the 
petals;  sepals  2;  style  "S-cleft— Portulacaceae,  29." 
Turning  to  p.  29  you  find  that  Claytonia  is  the 
only  genus  having  5  stamens,  and  that  this  plant 
must  be  Claytonia  perfoliata. 

The  little  plant  figured  above  (a)  evidently  an- 
swers to  the  description  of  the  Var.  exigua,  which 
is  now  considered  by  the  best  authority  to  be  a 
distinct  species.  The  stem  leaves  are  sometimes 
broad  and  united  at  the  base.  The  radical  leaves 
are  nearly  terete,  as  shown  in  the  figure.  This 
species  is  most  obviously  distinguished  from  the 
two  varieties  of  the  Cup-leaved  Claytonia,  by  its 
glaucous  leaves.  The  plants  are  often  smallei 
than  here  represented,  and  rarely  much  larger. 

Kellogg's  Lavatera,  or  Tree  Mallows,  an  ever-

the  Mallows  Family.  The  figure  at  the  bottom  of 
the  page  represents  one  of  the  flowers  cut  through 
the  center,  so  as  to  show  the  structure.  The  fruit 
of  a  very  common  weed  of  the  same  family  is  also 
shown.  The  most  common  native  plant  is  Sidalcea 
humilis,  described  on  page  32.  Hollyhock,  cotton, 
dkra  and  Abutilon  are  foreign  plants  of  this  order, 
common  in  cultivation.  The  latter  is  a  shrub  with 
drooping  flowers;  the  petals  incurved,  and  the 
stamens  sticking  out  (exserted).

You  may  recognize  in  the  picture  on  this  page  the 
likeness  of  one  of  our  most  troublesome  native 
weeds.  The  yellow  flowers  are  often  smaller  than 
here  represented,  and  the  upper  leaves  are  generally 
narrower.  Indeed,  this  plant,  along  with  many 
others  of  this  coast,  is  provokingly  variable  in  its 
appearance.  Pull  off  a  corolla,  and  a  single  un- 
divided style  is  uncovered.  Follow  this  down  into 
the  calyx,  and  you  discover  that  it  grows  from  be- 
tween four  seed-like  ovaries.  These  are  more  easily 
seen  in  an  older  calyx,  as  shown  at  a.  Now  it  hap- 
pens that  this  peculiar  compound  ovary,  together 
with  the  coiled  inflorescence,  belongs  only  to  plants 
of  the  order  Borraginacese.  A  coiled  inflorescence 
and  a  pistil  with  a  divided  style  is  found  only  in 
plants  of  the  order  Hydrophyllaceae.  Any  plant 
with  a  four-parted  ovary  and  regular  flowers  may 
be  sought  under  the  former  order.  Creeping  Helio- 
trope or  Blue  Weed  ( I/ciiotropium  Curassavicum)  is 
a  Borraginaceous  plant  with  ovaries  merely  4-lobed. 
The  Mint  Family  has  fruit  similar  to  that  of  the 
Borrages  (see  d  and  e  in  the  figure  on  p.  11),  but  the 
flowers  are  irregular.  The  Verbenas  are  distin-

and  a  4-lobed  ovary,  which  does  not  split  into  parts 

until  quite  ripe.     (See  a  in  the  left-hand  figure  on  page  11.) 

The  plant  figured  at  the  top  of  the  opposite  page  is  common  in  open  woods  throughout 
the  Coast  Ranges  and  the  foot-hills  of  the  Sierra  Nevada.  The  flowers  are  white,  tinged 
with  purple.  Each  of  the  three  incurved  petals  is  covered  with  hairs  on  the  inner  side, 
and  is  marked  near  the  base  by  a  depression  which  is  seen  upon  the  outside  as  a  project- 
ing boss.  This  is  called  a  gland,  and  is  one  of  the  characteristic  marks  of  the  genus. 
Since  the  three-cornered  ovary  is  superior,  we  at  once  refer  the  plant  to  the  order 
Liliacese,  where  we  again  read  the  characters  given  in  each  of  the  three  series.  The 
stamens  in  this  plant  are  hypogynous,  not  perigynous,  and  the  anthers  are  extrorse. 
Therefore,  SERIES  I  is  passed.  SERIES  III  is  excluded,  because  the  anthers  in  this  plant 
are  not  versatile.  Evidently  the  name  is  to  be  sought  under  SERIES  II,  which  is  divided 
into  three  sections.  You  now  see  why  you  should  have  dug  up  one  of  the  plants.  How- 
ever, you  can  decide  the  genus  without  knowing  that  the  plant  is  bulbous.  It  can  not 
belong  to  §  3,  since  one  of  the  two  genera  under  it  has  umbellate  flowers,  and  the  other 
solitary  flowers.  In  §  2,  the  perianth  segments  are  similar.  Our  plant  then  must  be  sought 
in  §  1,  and  under  the  head  "*  *  Perianth  segments  unlike,"  which  leads  to  Calochortus,

and  nodding  flowers  place 
it  in  the  first  di vision  of 

§  1,  Eucalychortus.  Our  plant  is  the  white  species.  The 
yellow  species  has  larger  flowers.  The  stiffly  erect,  open 
flowers  of  §  2  of  this  genus  have  a  markedly  different  ap- 
pearance from  the  species  here  figured;  yet  their  struc- 
ture is  similar.  The  spots  upon  the  petals  cause  them  to 
resemble  the  wings  of  butterflies;  hence  the  common  name  Butterfly  Tulip,  and  the  sec- 
tion, name

the  minute  flowers  on  a  scape  exceeding  the  leaves. 


ORDEE  3.     NYMPHJEACE-ffi. 

Aquatic  perennial  herbs,  with  peltate  or  deeply  cordate  leaves;  solitary  axillary  perfect 
flowers  on  long  peduncles.  Stamens  numerous. 

Water-Shield.  (Brasenia  peltata,  Pursh. )  May  be  found  in  ponds.  Its  elliptical,  pel- 
tate, floating  leaves  (green  above  and  brownish-red  beneath)  and  its  jelly-ccated  stems 
characterize  it  quite  well  enough. 

The  Yellow  Pond-Lily  (Nuphar  polysepalum,  EngL )  is  more  common. 


The  Order  Sarraceniaceae  is  represented  by  the  remarkable  Darlingtonia  California, 
or  California  Pitcher  Plant,  which  grows  in  cold  swamps  in  the  northern  part  of  the 
State,  from  Mount  Shasta  to  near  the  coast. 

Frankenia  grandifolia  grows  in  saline  soils,  and  may  be  known  by  its  opposite  sessile, 
obovate,  or  linear  oblanceolate,  small  leaves,  with  re  volute  margins;  and  by  its  small, 
pink  flowers.  It  may  be  distinguished  from  a  Silene,  which  at  first  it  seems  to  be,  by  its 
fewer  (4  to  7)  stamens  and  sessile  flowers. 

The  Order  FrankeniacesB  should  come  next  to  Caryophyllacece.  Fremontia  Califor- 
nica,  belonging  to  the  Order  Sterculiacese,  which  is  allied  to  the  Malvaceae,  is  most 
conveniently  described  here  also.  It  is  a  small  tree,  bearing  conspicuous  yellow  flowers 
in  the  axils  of  usually  broadly  cordate,  lobed  leaves.  The  apetalous  flowers  are  some- 
times 2  or  3  inches  across. 

The  Order  Capparidacese  is  represented  in  Santa  Barbara  County,  and  southward,  by 
homeris  arborea,  a  low  shrub,  bearing  bracteate  racemes  of  yellow  flowers,  the  pistils 
conspicuous  on  account  of  their  long  stipes.  The  flowers  of  this  plant  are  apparently 
like  those  of  the  Cruciferae,  and  its  proper  place  is  next  tc  that  order.  Capers  are  ob- 
tained from  a  cultivated  plant  of  this  order. 

The  Order  Styracaceee  is  represented  by  Styrax  Californica,  a,  pretty  shrub,  bearing 
clusters  of  nearly  rotate  white  flowers,  in  which  the  gamopetrJous  corolla  is  cut  down  to 
the  short  tube  which  is  adnate  to  the  tube  formed  by  the  stanens:  Calyx  truncate

On  the  left  above  is  represented 
an   opening   bud   of    Eschscholtzia. 

I  The  cap-like  calyx  has  been  split  at 

the  bottom  and  shoved  upward  by 
the  expanding  petals.  Next  to  this 
bud  is  an  open  flower  of  Meconopsis  and  one  of  its  nodding  buds.  Behind  the  flower, 
and  projecting  above  it  to  the  right,  is  a  stem  from  which  the  petals  have  just  fallen. 
The  slender  filaments  bending  to  one  side,  as  they  often  do,  show  the  curious  pistil 
which  in  time  becomes  the  pretty  fluted  capsule  seen  below.  To  the  right  of  the  Meco- 
nopsis pod  is  the  three-sided  capsule  of  Platystigma  lineare.  The  stem  should  have  a 
few  hairs  upon  it.  The  two  flowers  with  hairy  stems,  the  nodding  buds  below,  and  the 
rough  seed  pod  above,  belong  to  Platystemon.  Observe  the  three  caducous  sepals,  just 
ready  to  drop  from  the  opening  bud.  The  smooth  plant  on  the  right  is  Platystigma 
Californicum.  If  you  choose  you  may  call  this  the  Smooth  Platystigma,  and  the  other 
species,  with  the  triangular  pod,  Hairy  Platystigma.  The  exceedingly  prickly  Bristly 
Argemone  is  represented  on  the  right,  below,  by  a  bud  and  a  couple  of  bracts.  A  pistil 
with  its  white  prickles  is  imperfectly  shown  against  one  of  the  bracts. 
The  Order  Papaveraceae  is  characterized  by  flowers  with  2  or  3  caducous  sepals, 


20b  FAPAVERACE2E.       (POPPY    FAMILY.) 

twice  as  many  free  petals  in  two  sets,  indefinite,  visually  numerous,  free  stamens,  and  a 
compound  pistil.  In  Eschscholtzla  the  sepals  are  united,  and  the  stamens  adhere  to  the 
claws  ot  the  petals. 

This  small  but  interesting  order  of  plants,  with  the  exception  of  one  species,  is  con- 
fined to  the  northern  hemisphere.  Fifteen  species,  belonging  to  eleven  genera,  are  natives 
of  the  United  States,  and  several  European  species  have  become  naturalized.  Esch- 
scholtzia  and  Platystemon  are  the  most  widely  distributed  of  the  California  genera. 

Romneya  Coulteri  is  a  half  shrubby  plant,  with  smooth  pinnatifid  leaves  and  very  large  white  flowers 
(3,  4,  or  even  6  inches  across) ,  a  native  of  the  coast  from  San  Diego  to  Santa  Barbara  County. 

Arctomecon  is  another  white-flowered  plant,  with  somewhat  hairy,  nearly  entire  leaves;  the  petals 
persistent;  found  in  south  Nevada  and  Utah. 

Canbya,  a  recently  discovered  plant  of  south-east  California,  is  the  smallest  of  the  order,  being 
scarcely  an  inch  in  height.  The  small  white  petals  are  persistent. 

Papaver  Somniferum,  a  native  of  Asia,  furnishes  opium,  which  is  the  dried  juice  of  the  plant.  A 
•variety  of  this  species  is  cultivated  in  this  State  for  the  seeds,  from  which  is  expressed  poppy  oil,  used 
by  artists.  This  oil  is  also  used  as  a  substitute  for  olive  oil  in  the  preparation  of  salads,  etc.

OKJJKK  ANACARDIACE-SI  is  represented 
by  the  well-known  Poison  Oak  or  JRhus  diversiloba, 
a  slender,  sometimes  climbing,  shrub,  resembling 
the  eastern  Rhus  toxicodendron,  which  is  also  often 
called  Poison  Oak,  but  is  more  commonly  known 
as  Poison  Ivy.  The  eastern  Sumac  belongs  to  the 
same  genus.  There  are  three  other  species  of 
Rhtis  in  the  State.  The  Pepper  tree  (Schinu* 
moile),  so  commonly  cultivated  as  an  ornamental 
shade  tree,  belongs  to  this  order. 

ORDER  20.     LEG-UMINOS^E. 

The  single  and  simple  free  pistil  becoming  a  legume  in  fruit,  the  alternate  leaves  with 
stipules,  and  in  our  genera,  the  papillionaceous  corolla  with  10  stamens,  mark  this  order, 
one  of  the  largest  and  most  important  in  the  vegetable  kingdom. 

Flowers  irregular.  Calyx  3-5-cleft  or  toothed,  persistent.  Corolla  of  5  petals,  the 
upper  larger  and  always  external,  covering  the  lateral  pair  in  the  bud,  and  these  cover- 
ing the  lower  pair,  which  are  more  or  less  united,  forming  a  keel  which  encloses  the 
stamens  and  pistil.  Filaments  10,  rarely  5,  commonly  united  around  the  pistil,  either 
all  united  or  nine  and  the  upper  one  free.  Ovary  forming  a  pod  with  a  single  row  of 
seeds  attached  to  one  side;  style  usually  inflexed  or  curved.  In  Cards  the  upper  petal  is 
small  and  enclosed  by  the  wings.  In  Amorpha  there  is  but  one  petal. 

Suborder  Caesalpineae  is  marked  by  the  upper  petal  enclosed,  and  distinct  stamens. 

Suborder  Mimoseae  has  regular  flowers  and  usually  many  conspicuous  stamens.

This  order  is  remarkable  for  the  number  of  useful  and  beautiful  jjlanta 
which  belong  to  it.  Pease,  beans,  lentils,  peanuts,  clover,  alfalfa,  etc., 
furnish  food  for  man  and  domestic  animals.  Tropical  plants  of  this 
order  supply,  among  others,  the  following  articles  of  commerce:  Gum 
arabic,  gum  Senegal,  gum  copal,  dragon's-blood,  indigo,  logwood,  brazil- 
wood, rosewood,  tamarind.  Many  species  have  medical  value,  as  senna, 
catchu,  copaiba,  etc. 

There  are  over  6,000  species  of  leguminous  plants,  mostly  tropical. 
About  350  species  are  natives  of  the  United  States,  more  than  half  of 
which  are  found  in  California.  Only  4  or  5  species  are  common  to  this 
coast  and  the  Atlantic  States,  and  these  have  forms  peculiar  to  each 
coast.  Our  180  species  are  grouped  under  14  genera,  while  the  150  species 
of  the  East  (I.  e.,  the  Mississippi  States  and  eastward  to  the  Atlantic), 
represent  50  genera.  There  are  about  40  species  of  lupine,  and  the  same 
number  belonging  to  the  genus  Astragalus,  growing  within  the  limits  ol 
this  State.  Only  two  kinds  of  the  former  and  4  of  the  latter  grow  east 
cf  the  Mississiniri.  The  latter  is  the  largest  American  genus  of  the

order,  the  species  within  the  United  States  numbering  about  150,  nearly  all  of  which 
belong  west  of  the  Rocky  Mountains.  We  have  about  25  kinds  of  clover;  only  3  or  4 
species  are  natives  of  the  East.  Hosackia,  numbering  28  species  in  our  whole  country, 
25  of  which  grow  here,  is  not  represented  in  the  East  at  all.  On  the  other  hand,  the 
large  genus  Desmodium,  numbering  in  the  East  19  species,  has  no  representative  west  of 
the  Rocky  Mountains.  Pickeringia  is  probably  not  found  beyond  the  boundary  of  Cali- 
fornia. The  great  Australian  genus  Acacia,  numbering  there  nearl}7  300  species,  is 
represented 'in  Southern  California  by  a  small  tree  (A.  Greyyii),  and  in  the  East  by  an 
herb.  Possibly  30  species  are  cultivated  for  shade  trees.  Honey  Mesquit,  or  Algaroba 
(Prosopis  juliflora)  and  Screw-pod  Mesquit,  or  Tornilla  ( P.  pubetcens),  are  small  trees  of 
Southern  California.  Prosopis  and  Acacia  belong  to  the  Suborder  Mimoseae.  All  the 
plants  here  described  (except  Cercu)  belong  to  the  Suborder  Papilionacese,  which  is  dis- 
tinguished by  flowers,  like  those  of  the  pea,  as  before  described. 

Cercis,  which,  by  mistake,  is  not  described  in  the  proper  place,  belongs  to  the  Sub- 
order Csesalpineae,  in  which  the  side  petals  enclose  the  upper  one  and  the  stamens  are  free.

OBDBB  42.     SOLANACEJE. 

Herbs  or  shrubs,  with  alternate  leaves  and  no  stipules,  regular  5-merous  flowers  on 
bractless  pedicels,  a  single  style  and  a  2-celled  ovary;  the  fruit  a  many-seeded  berry  or 
capsule. 

This  small  order  of,  perhaps,  not  more  than  a  dozen  species  west  of  the  Sierra  Nevada, 
and  less  than  70  in  North  America,  is  remarkable  for  the  diversity  of  properties  exhibited 
by  its  members,  and  the  almost  universal  use  by  man  of  several  of  its  species.  At  first 
view,  the  classification  seems  absurd  which  puts  fiery  Cayenne  pepper  and  insipid  egg 
plants,  the  wholesome  tomato  and  deadly  night-shade,  nutritious  potatoes  and  poisonous 
tobacco  together  in  one  famity.  A  careful  examination  shows  that  these  seemingly  very 
different  plants  are  much  alike  after  all.  The  four  most  important  plants  of  this  order — 
potato,  tobacco,  red  or  Cayenne  pepper,  and  tomato — are  natives  of  tropical  America, 
and  were  consequently  not  used  in  the  Old  World  before  the  sixteenth  century.  The 
following  ornamental  plants  of  the  order  are  common  in  cultivation:  Jerusalem  Cherry 
(Solanum  Pseudo-Capsicum),  a  small  shrub,  with  red  berries;  Jasmine  Solanum  (.9.  Jas- 
minoides),  a  shrubby  climber,  with  a  profusion  of  nearly  white  blossoms  a  little  smaller 
than  those  of  the  potato;  the  well-known  Matrimony  Vino  (Lycium  vulrjare}-,  Tree 
Datura  or  Stramonium  (Datura  arborea),  with  hanging  flowers  six  or  seven  inches  in 
length;  Cestrum,  a  shrub  with  drooping  tubular  red  flowers  in  terminal  bunches;  and 
Petunia,  with  funnel-form  corollas  of  various  colors. 

Solanum  2Tanti,  Gray,  grows  along  the  coast  from  Santa  Barbara  southward,  and  has  been  reported 
from  Lako  County.  It  is  more  herbaceous  than  S.  umbelliferum,  and  may  be  distinguished  with  the  aid 
of  a  lens  by  its  simple  glandular  hairs,  instead  of  the  branching  hairs  of  the  latter  species. 

Physalis  or  Ground  Cherry  may  bo  found  in  cultivated  ground.  Its  berries  are  enclosed  by  an 
inflated  calyx. 

Datura  Uletdoides,  DC.,  grows  on  the  Salinas  River  and  southward.  The  flowers  are  white  or  violet 
tinged,  and  C  to  8  inches  long,  with  a  wide  border;  the  capsule  nodding.

This  large  order,  numbering  nearly  2,000  species,  is  remarkable  for  the  great  Oeauty  of 
fts  flowers,  and  for  the  impartial  distribution  of  its  species  over  the  whole  world.  Over 
300  species,  belonging  to  37  genera,  are  natives  of  the  United  States.  About  75  species 
s;row  east  of  the  Mississippi,  and  about  100  west  of  the  Sierra  Nevada  in  this  State.  The

most  important  American  genera  are  Pentstemon,  75  species,  found,  with  one  exception, 
only  iu  North  America,  and  mostly  within  the  limits  of  the  United  States  between  the 
Rocky  Mountains  and  the  Sierra  Nevada;  Mimulus,  represented  in  other  countries,  but 
most  largely  in  North  America,  where  there  are  30  species,  about  two  thirds  of  which 
gro\v  in  California,  west  of  the  Sierra  Nevada,  only  2  species  reaching  the  Atlantic 
States;  Orthocarpus,  24  species,  all  North  American,  except  one,  and  west  of  the 
Mississippi,  16  belonging  to  California;  Gerardia,  24  species,  mostly  in  the  Atlantic 
States,  and  none  reaching  the  Rocky  Mountains;  Castilleia,  23  species,  2  Asiatic,  3  in  the 
Atlantic  States,  and  8  or  9  in  California;  Pedicularis,  a  large  genus,  mostly  in  the  arctic 
regions  and  on  high  mountains  of  the  temperate  zone,  28  American  species;  Collinsia,  15 
species,  all  California^,  except  two,  which  grow  in  the  Mississippi  Valley.  Several 
showy  species  of  shrubby  Veronicas  are  cultivated.  This  large  genus,  numbering  40 
species  in  New  Zealand  alone,  is  represented  in  the  United  States  by  only  a  few  obscure 
herbs.  Digitalis,  commonly  cultivated  under  the  name  of  Foxglove,  has  run  wild  about 
Humboldt  Bay  and  in  the  Willamette  Valley. 

Many  plants  belonging  to  the  genera  Pentstemon,  Collinsia,  and  Mimulus  are  culti- 
vated on  account  of  their  beautiful  flowers.  Pentstemons  are  mostly  confined  to  hilly  or 
mountainous  districts.  Collinsias  grow  everywhere.  Most  species  of  Mimulus  prefer 
moist  places,  but  the  only  shrubby  species,  M.  glutinosus,  grows  on  dry,  rocky  hillsides- 
Two  species  of  Verbascum  (Mullein)  are  found  In  the  State,  but  probably  not  within  our  limits;  V. 
Thapsus,  L..  with  woolly  decurrent  leaves  and  V.  mrgatvm,  Withe.,  distinguished  by  nearly  smooth  not 
decurrent  leaves  and  violet  bearded  filaments.

PREFACE. 


THIS  Key  is  preliminary  to  a  West  Coast  Botany  for  beginners,  which  will  probably 
be  completed  within  three  years.  The  object  in  publishing  this  skeleton  in  advance  is 
twofold :  it  will  be  serviceable  in  connection  with  the  Popular  California  Flora,  while  ita 
use  will  disclose  mistakes  and  weak  places  which  can  be  corrected  and  strengthened  for 
the  betterment  of  the  final  work. 

The  material  has  mostly  been  drawn  from  Gray's  Synoptical  Flora  of  North  America 
and  the  California  Botany.  Free  use  has  also  been  made  of  Gray's  and  Watson's  Contri- 
butions to  American  Botany;  Greene's  monographs  in  the  Bulletin  of  the  California 
Academy  of  Sciences,  and  the  contributions  of  these  and  other  authors  in  Coulter's 
Botanical  Gazette  and  the  Bulletin  of  the  Torrey  Club. 

The  intention  has  been  to  describe  all  polypetalous  and  gamopetalous  plants  growing 
in  the  region  indicated  on  the  title  page,  except  those  belonging  to  the  orders  Umbellifera 
and  Composite ;  also  all  the  species  in  the  endogenous  orders  Alismacese,  Orchidace®, 
Iridacea  and  Liliacese.  The  scope  of  the  West  Coast  Botany  will  be  a  little  broader, 
including  some  of  the  Apetalae  and  possibly  a  tribe  of  the  Composite.  The  introductory 
lessons  and  glossaries  will  be  more  ample  than  those  of  the  California  Flora. 

I  shall  be  very  thankful  for  notes  of  omissions,  corrections,  criticisms  and  sug- 
gestions.

DIRECTIONS  FOR  THE  BEGINNER 


After  you  have  carefully  examined  the  plant  and  at  least  mentally  described  every 
part  of  it,  read  tho  first  lino  of  the  k&y  on  the  opposite  page.  If  the  sepals  and  petals 
together  number  8  or  10— as  is  usually  tho  case — then  the  plant  belongs  to  CLASS  I., 
which  refers  us  to  the  prominent  heading  below,  under  which  we  read,  "  Calyx  and 
corolla  both  present."  If  so,  read  the  next  line,  which,  we  will  suppose,  does  not  fit  our 
plant ;  then  tho  petals  must  be  united,  and  wo  turn  to  DIVISION  2,  page  9,  where  we 
aro  called  upon  to  say  whether  the  ovary  is  inferior  or  not.  Suppose  it  is  superior. 
Turn,  then,  to  "  B.  Ovary  superior."  But  our  flower  is  one-sided,  so,  instead  of 
searching  under  "1.  Flowers  regular  or  nearly  so,"  we  look  ahead  till  our  eyes 
catch  on  pago  10,  the  similar  line,  "  2.  Flowers  irregular:  style  1 ;  stigma  en- 
tire or  2-lobed."  Strangely  enough  there  is  but  one  style,  and  there  are  two  flat  stig- 
mas. The  leaves  being  opposite  we  pass  the  first  line  and  try  the  next,  having  tho  same 
marginal  distance,  reading,  "  Leaves  opposite  or  whorled:  stamens  2  or  4."  Heading  the 
three  lines  under  this  head,  beginning  with  the  word  "Ovary,"  we  easily  determine  from 
the  negative  evidence  (tho  ovary  not  in  4  pieces;  the  flowers  not  small,  or  in  spikes)  that 
the  plant  belongs  to  the  order  Scrophulariacere,  pago  93.  Wo  are  there  confronted 
*  by  another  key.  Tho  leaves  of  our  plant  not  being  alternate,  we  must  look  under  "  B," 
Reading  the  lines  marked  with  asterisks  we  take  the  first,  for  our  plant  has  4  stamens. 
We  then  read  all  the  lines  under  this  head  and  decide  that  our  genus  must  be  No.  10; 
viz.,  "10.  MIMULUS,  Linnaeus,"  which  we  find  on  page  98.  Our  plant,  then,  is  one 
of  the  40  species  of  Mimulus  there  named.  Fortunate  indeed  are  we  if  it  happens  to  be 
one  of  the  distinctly  marked  species  liko  Mimulus  glutinosus,  the  Shrubby  Mimulus;  or 
Mimulus  cardinalis,  the  Cardinal  or  Scarlet  Mimulus.  In  any  event  we  work  with  thia 
key  as  with  tho  others.  The  chief  heads  aro  indicated  by  stars.  Suppose  tho  corolla  is 
yellow  but  the  plant  not  viscid ;  then  it  must  bo  sought  under  the  5-starred  head.  Here 
we  must  read  all  tbe  lines  beginning  with  "Leaves."  Having  reached  a  conclusion,  we 
look  up  the  species  under  the  number  given  at  tho  end  of  the  line ;  say,  No.  23,  where 
we  find  a  few  more  words  descriptive  of  Mimulus  luteus.  We  next  look  in  the  index  for 
"  Mimulus  "  and  there  find  a  reference  to  p.  92  of  tho  Popular  Flora,  where  there  is  a 
more  ample  description  of  the  species.  Finally  we  turn  to  the  Glossary  of  Generic  and 
Specific  Names,  where  we  leam  that  mimulus  means,  ape,  or  mimic  ;  and  luteus  means, 
yellow.  Perhaps  Linnaeus,  who  delighted  in  fanciful  names,  saw  in  the  gaping  corolla  a 
monkey-like  grin.  Since  there  are  many  yellow  species  now  known,  the  name  is  not 
•ignificant ;  but  wo  may  call  it  the  Common  Yellow  Mimulus,  or  Monkey  Flower.
